Hi folks,
Welcome to a new Friday and a new issue! Nothing major to report, just the usual stream of news which I tried to compact for you :-) Enjoy!
Windows Downdate tool lets you 'unpatch' Windows systems
Researcher Alon Leviev has released his Windows Downdate tool, which can be used to downgrade Windows 10, Windows 11, and Windows Server systems to make them vulnerable to well-known vulnerabilities again. It's available as a Python script or a Windows executable, and has handy pre-sets to bring your target system back to being vulnerable to a specific CVE. You can find the Github repo here.
Of course, in order to do any of this you already have to own the system to a large degree. But considering the machine will keep saying it's "fully up to date", it might be a powerful persistence mechanism.

1Password: the password manager with (to me) the best UX
I'm not going to write a long marketing-heavy paragraph on this one. I just love using 1Password. The UX, the support, the integrations, it all works wonderfully. Highly recommended. (Sponsored)
